# BBScore encoder — wiki_dim8

BBScore encoder checkpoint (latent_dim=8) trained on Wikisection, used for the
Brownian Bridge coherence score in the [simpsy](https://github.com/bVendeville/simpsy)
text simplification evaluation library.

## Usage

```python
from simpsy import evaluate

df = evaluate(
    ["The cat sat on the mat. It watched the mouse. Then it pounced."],
    families=["bbscore"],
    # simpsy reads the checkpoint from SIMPSY_BBSCORE_HF_REPO, defaulting
    # to this repo once wired in as the simpsy default.
)
```

Or point simpsy at this repo explicitly:

```bash
export SIMPSY_BBSCORE_HF_REPO=BVendeville/bbscore-wiki-dim8
```
